How to make class member function a stream function using boost

Question

I am going to write an adapter class. This class has an xmlrpc-c server (abyss server). I want to start the server by creating a new thread, and the thread function is a member function of XMLThreadFun() .

When I try to use the code below, there is an error in the implementation string of the adapter constructor:

 /usr/include/boost/bind/bind.hpp:69:37: error: 'void (Adapter::*)()' is not a class, struct, or union type 

Can someone tell me how to solve this error or how to achieve my goal? I really appreciate that.

Below is my code snippet:

 #ifdef _MSC_VER #pragma warning( disable : 4503 4355 4786 ) #else #include "config.h" #endif #include "quickfix/FileStore.h" #include "quickfix/SocketInitiator.h" #include "quickfix/SessionSettings.h" #include "Application.h" #include <string> #include <iostream> #include <fstream> #include "quickfix/SessionID.h" #include "quickfix/Session.h" #include "getopt-repl.h" #include <cassert> #include <xmlrpc-c/base.hpp> #include <xmlrpc-c/registry.hpp> #include <xmlrpc-c/server_abyss.hpp> #include <boost/thread.hpp> #include <boost/date_time.hpp> using namespace std; class theClient : public xmlrpc_c::method { public: theClient() {} theClient(FIX::SocketInitiator* initiator) { set<FIX::SessionID> s(initiator->getSessions()); set<FIX::SessionID>::iterator myIterator; for (myIterator = s.begin(); myIterator != s.end(); myIterator++) { string str(myIterator->getSenderCompID()); clientname = str; } } void execute(xmlrpc_c::paramList const& paramList, xmlrpc_c::value * const retvalP) { *retvalP = xmlrpc_c::value_string(clientname); } private: string clientname; }; class Adapter { private: xmlrpc_c::registry myRegistry; xmlrpc_c::methodPtr XMLRPCMethodP; xmlrpc_c::serverAbyss webServer; boost::thread webServerThread; public: void initWebServer(string rpcHost, string rpcPort); void XMLThreadFun(); Adapter(string rpcHost, string rpcPort); }; Adapter::Adapter(string rpcHost, string rpcPort) : myRegistry(), XMLRPCMethodP(new theClient), webServer(myRegistry, 8181, "/tmp/xmlrpc_log"), webServerThread(boost::bind(&Adapter::XMLThreadFun, this, &webServer)) { initWebServer(rpcHost, rpcPort); } void Adapter::XMLThreadFun() { webServer->run(); } void Adapter::initWebServer(string rpcHost, string rpcPort) { webServerThread.join(); }

You will need to use boost :: bind to call the member function as a stream. Sort of

 class MyClass { public: void Start(); void DoStuff( int limit ); }; MyClass foo; boost::thread thread1( boost::bind( &MyClass::Start, &foo ) ); boost::thread thread2( boost::bind( &MyClass::DoStuff, &foo, 30 ) ); // threads do stuff here thread1.join(); thread2.join(); 

In particular, it looks like you would change

 webServerThread( boost::bind( &Adapter::XMLThreadFun, this, &webServer) 

to

 webServerThread( boost::bind( &Adapter::XMLThreadFun, this )

No need to use boost :: bind

 boost::thread thread2( boost::bind( &MyClass::DoStuff, &foo, 30 ) ); 

is equivalent to:

 boost::thread thread2( &MyClass::DoStuff, &foo, 30 );
